The correct answer is D. amount of collagen present.
Explanation:
As fibroblasts begin to enter the wound site, migrate and proliferate. They lay down the collagen matrix in the wound site. Collagen deposition is important because it increases the strength of the wound. The tensile strength is ergo highest with the most collagen present.
Well if it could not adapt it would die. Either it would be killed by a more superior species, natural selection would take its course, or it just wouldn't be able to survive.
